Water is the most abundant, yet possibly the most overlooked, substance in the body, as it represents 45 to 60% of an adult's total body weight. It plays a vital role in all bodily processes by providing a universal medium for chemical reactions, lubrication, nutrient delivery, waste disposal, heat dispersion and temperature regulation.

In order to maintain the fluid balance within the body water gain needs to equal water loss. Exercise significantly increases fluid loss which can reach levels of up to 4 liters per hour during heavy work-outs. A loss of body mass through dehydration of as little as 2% significantly impairs performance which emphasizes the importance of the maintenance of hydration, especially during exercise.
